UK Gilt Yields Surge as Iran War Sparks Rate Hike Frenzy

2026-03-23 08:39 By Joana Ferreira 1 min. read

The UK’s 10-year gilt yield surged above 5%, reaching its highest level since July 2008, as the Middle East conflict sent energy prices soaring and intensified expectations of aggressive Bank of England rate hikes.

Shorter-term 2-year yields jumped above 4.6%, a peak since February 2024, while 30-year yields hit 5.6%, the highest since September 2025.

British bonds have been among the worst performers since the US-Israel strikes on Iran, with the UK’s heavy reliance on imported energy amplifying vulnerability to supply shocks.

Markets now price in four quarter-point BoE hikes this year, a stark reversal from pre-conflict expectations of two rate cuts, as policymakers pledge to combat inflation.

The spike in borrowing costs is straining the government’s fiscal targets, prompting Prime Minister Keir Starmer to call an emergency meeting with BoE Governor Andrew Bailey on Monday to address the crisis.

UK Gilt Yields Fall Amid US-Iran Deal Uncertainty
UK 10-year gilt yields fell to 4.85%, retracing part of Monday’s nine-basis-point rise, as oil prices declined and investors adopted a wait-and-see approach amid uncertainty over Middle East peace efforts. US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu gave differing accounts of a call about the Lebanon conflict, with Trump saying he urged both sides to stop fighting, while Netanyahu’s version was less definitive. This follows reports that Iran paused US talks, demanding an end to Lebanon clashes as part of any deal, though Trump claimed discussions with Iran were advancing quickly. On the monetary policy front, investors are anticipating nearly two Bank of England interest rate increases this year, with the first hike fully priced in for September, as policymakers navigate the dual challenge of rising inflation and a labor market that is showing signs of gradual weakening.

UK Gilt Yields Jump on Inflation Fears
UK 10-year gilt yields climbed back above 4.9%, recovering from over one-month lows, as renewed US-Iran tensions pushed oil prices higher and intensified inflation concerns. Iran’s Tasnim News Agency reported on Monday that Tehran would halt negotiations with the US over Israeli strikes on Lebanon and fully close the Strait of Hormuz, accusing Washington of "violating the ceasefire on all fronts." Over the weekend, both sides exchanged proposals to revise a draft deal to extend the ceasefire and reopen the Strait of Hormuz, though progress remained uncertain. The geopolitical uncertainty prompted investors to modestly raise expectations for further Bank of England rate hikes this year, with markets now pricing in almost two increases, with the first one fully priced in September. Economically, UK house prices fell 0.6% in May, according to Nationwide, a steeper decline than the expected 0.1% and the largest monthly drop since June 2025.
